'Defence' forces are insurance policies (well, cavorting around the Missle East aside...). How many trillions were spent on ICBMs? How many times did they get used?
Joe Public probably wouldn't react well if Boris Badenov and Chairman Jin were flaunting flash new stealth weapons that could not be countered, regardless of the platform. The 'arms race', whilst it may have slowed a bit, is still running.
So you get with the program or you get left behind. For the 'Leader of the Free World', and us lesser hangers-on, there's no option.
